First of all, let me say that I enjoy using the Associated Press application for Blackberry. I think it is a great application. However, it is significantly different from Yippidu WorldNews. Yippidu WorldNews is an aggregator news app since it collects article snippets from major content providers and drives traffic back to the original publishers.

In any event here are some features that make Yippidu different:

- quick access to relevant information: we collect categorized articles from the top 10 news providers for each country we cover. That eliminates noise deriving from overly local info or irrelevant or politically biased information. Also, we automatically extract the "hot topic" labels (using text clustering techniques) from the current Headelines web pages of the collected publications (every 30 mins). This provides an immediate overview of what is important now.
- search: you can search all info for a specific country or for a single category of information for a single country
- tags: for each article we automaticlly identify important tags that you can click on to find all articles sharing the same tag
- related articles: for each article you have links to similar articles
- bookmarks: you can bookmark a search or a tag to repeat the same search or tag query later on. You will find your bookmarks in the personalized news section
- monitors: you can create monitors by entering keywords to filter and catch incoming articles (either in the background or when running a search) that contain those keywords. Monitors are great to stay abreast on what is being said on a specific topic.
- native twittering: Twitter apis are embedded so you can twitter from Yippidu without using the browser.
Hopefully, this covers major differences.

We tried very hard to limit memory and object growth in Yippidu WorldNews. We added a Statistics menu item to monitor objects and flash memory statuses (you can also activate some limited optimization). Please let us know of any issues.
